I have a question regarding the Nichia 144A LED´s.
I want to build a Light Bar for my workshop. I want to use 3 or 4 ×144A 9050 sm573 LED´s in series with this driver (http://www.banggood.com/250W-12-50V-Adjustable-10A-Aluminum-Board-Power-...LED-Driver-Module-p-1026633.html?rmmds=myorder). I want to drive the LED´s with max 3A (total W max all LED´s together 100-150W). My question is if the Aluminium Profile is enough to handle the heat from the 144A´s (LED on Djozz Nichia MCPCB fitted on the Alu Profile with thermal glue). And i hope that someone can tell me which TIR for the 144A is frosted an has the widest spread?


I am not good with paint software but i hope it is possible to see what i want to build.

Yes, that setup should work, you might need to add a fan blowing through the inside of the tube to keep things cool but that is not hard.

Far as the tir goes, there are a lot of options, just find something with a wide beam angle and that is sized to fit the XM-L. I have only really messed with the narrow beam angle TIR’s myself but I did get a 90 degree tir that gave a nice even flood and they have even wider ones as well.

You also will very possible have to make some kind of spacers / centering ring for the TIR to mount to the top of the tube, it is unlikely that it will be just the right height to “snap” the tir into place.

FYI, not all XML TIR suitable for 144A. I’ve tested some TIR meant for XML and they don’t fit. That’s because 144A emitter is slightly taller than XML. You better start searching for XHP50/70 TIR. And as a bonus you’ll get better beam profile since XHP50/70 has rather severe artifact problem. All good TIR designed for XHP50/70 overcome this problem with some kind of colour mixing put into the design.
For workshop application I really like the Jenny CY from Ledil, it’s an excellent fit for 144A based on the data sheet. Haven’t try it yet
144A designed for high bay application and so does Jenny CY. It will give you a rounded square even illumination on the floor.

If you need even wider beam angle:

Those aluminum profile won’t be enough to cool 3 × 144A @3A if you want to keep the Tj lower than 85C. Edit: I didn’t see your annotations.
For more surface area you can drill as many as possible holes on it. The maximum surface are gained with hole diameter = aluminum profile thickness.

Are you sure?
It’s 2 meters long and at least 40 × 60 mm.
Some holes may be good to have some airflow though.

Ah…..that explains. I didn’t check the annotations at the picture. To me, judging from the picture’s scale, it’s about 50cm or something.
If it’s 200cm then it should be OK. Smile
Thanks for correcting Jeroen.

Theonlydocc, here’s a scaled drawing I made for you. If you want to update the dimensions, just let me know.

Yep, they look good, have not pulled them apart yet but no damage, it was well packed.

Can’t wait to change my EDC S2+ over to one of these, might rebuild it while in there with the latest TA driver.

That’s some pretty fast shipping for this time of the year, good job!

I’m hoping for a nice incandescent triple 219C 3000K in Reylight’s X6 Ti host, been missing that warm tint for outdoors.

Thanks for doing this guys! Thumbs Up

I’m jealous, TA!
My package is in the Netherlands for two days now, but not delivered yet (have been home all day yesterday). The various tracking sites tell me that the package is untrackable at the moment, very useful Sad

I didn’t expect it quite so quick myself but DHL is pretty quick once they get it.

Going to start sorting and packing them in a little while.

Guys, I found something….
Check this picture, even the already cool white of 5700K still didn’t match the sunlight due to the lack of UV (good thing for fabrics and art museum). The brightener agent in the paper reacted strongly under the sunlight.

I’ll replace some pictures in the OP with this one. Much better for comparison purpose

….And there isn’t much difference between sm403 and sm503. Maybe that’s why Nichia doesn’t produce Ra9050 in sm45x

Ok, just got done sorting, packing and shipping all the orders. The tracking numbers should have either been delivered to your paypal email address or with a PM here depending on how you paid.

Now to get a second wind and start playing with mine, Got several lights I am building as gifts for Christmas that I am going to try them out in.

Interesting finding. Do you happen to know the brightness of that paper?

I can’t measure it but it’s obvious that the paper turned blueish, especially the paper area near the colour cards which was wetted with glue stick.

Pity there’s no cyan / turquoise samples in between blue and green there.
No purple either..

That’s all I could get from the paint store. Next time I’ll try to get more complete colour cards. Took me 2 hours just to get them glued evenly. But now we know that UV plays important role in making anything looks more natural, something not included in CRI colour sample.

It comes from experience I guess. Having been doing internet sales for some time you learn a few tricks to speed up the process.

Luckily everyone on BLF sent payment correctly with all the needed information included with it, this saves me a ton of time. Thanks for ya’lls part in that!

That’s a big can of worms you opened there. Thankfully, my windows filter UV so I can just stay inside and ignore the whole thing Wink

So will the next step in high CRI be to add a UV emitter next to those nichia? I can picture people bragging about how fast their light gives them sunburn.

You know, UV ist not so great for the eyes. I would wear sunglasses outside in the tropics. The picture with sunlight would probably be very similar to the one from the 573 Nichia with a UV-Filter in front of the lens(Red, deep blue and Cyan color will still be better though).

Sure, he’s my friend. I can get all the unused colour cards he has. Unfortunately those are also the least complete too. Less card with more complete colour samples should be better.

I think it’s mainly caused by the glue spray I used. I wiped the excess sticky stuff on the cards with wet towel, thus the smear marks. Some materials respond stronger to UV.

Please don’t, high CRI minus the UV is much better for our eyes

Actually the cool white 144A has the highest violet-blue (480nm) spectrum proportion compared the other high CRI Nichias (> than 40%). But still far away from the UV region
